Vibrationsdämpning av värmepump
Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

Hög avkastning till låg risk : En jämförande studie mellan aktieportföljers innehåll och prestation
Syfte: Studera sju portföljer och notera den bästa typen av portfölj med högst avkastning till lägst risk.Metod: Sekundärdata är grunden för uträkning av samtliga portföljers avkastningar, risker och korrelation. Studien är deduktiv med kvantitativa inslag av kända teorier av nobelpristagare i ekonomisk vetenskap. Slutsats: Studien visar att stora bolag i olika branscher är ett vinnande portföljinnehåll för denna studie. Stora bolags aktier har visat högre avkastning till lägre risk jämfört med små bolag under studiens tid då ekonomiska kriser drabbade marknaden. Den mest presterande portföljen var därför storbolagsportföljen.Vidare forskning: Längre tidsperspektiv och nya teorier som Jensens alfa samt Treynorkvot är av intresse för vidare forskning för att styrka vår slutsats..
Finansiella nyckeltal i svenska börsbolag - En empirisk studie av historiska värden och förekomsten av konvergens till långtidsmedelvärden
Practitioners of financial statement analysis are dependent on key ratios in a multiple number of situations, one in particular being equity valuation. A lack of historical benchmarks, and knowledge regarding the time series behaviour of such ratios, has been identified regarding Swedish companies. Therefore, this study sets out to provide such data and knowledge. Companies listed on the Stockholm Stock Exchange are examined over the period 1979-2009 where the sample is divided into nine industry groups. Historical values for eight common key ratios are documented with regards to median, mean, standard deviation and percentiles.
En studie i RR 29 / IAS 19:s förändring och utfall
The pension audit has been a hot topic for the listed companies for the last years. New rules have been applied which have caused discussions and difficulties for the companies. EU?s ministry of council accepted the so called IAS 2005 Regulation on the 7th June 2002. This means that all companies listed on the stock market must follow IAS regulations in their consolidated accounts latest 2005.
Optimal kapitalstruktur : En undersökning tillämpad på skandinaviska och tyska företag
This paper describes and develops a trade off model of optimal capital structure by Bradley et al. (1984). The model is then tested to examine how changes in corporate tax rates affect the optimal capital structure of firms. Based on theoretical implications of the model, four hypotheses are derived stating that firms? optimal debt-to-value ratio is (1) negatively related to financial distress costs, (2) negatively related to non-debt tax shields, (3) negatively related to firm volatility and (4) positively related to the corporate tax rate.
Streamad Tv ? komplement eller konkurrent för linjär Tv? : En studie om preferenser bland män och kvinnor i olika åldrar
Few would disagree that the media landscape has undergone significant changes the last decade. From bulky computers and plain mobile phones to portable High-Definition computers and multi-functional smartphones. Other media, such as newspapers and music, have evolved and prospered in a digitalized environment. The constant urge to digitalize aspects and functions of our daily lives seems almost instinctive. Television has taken further steps into this environment as it is now accepted and featured via the Internet.

Torkat bioavfall som jordförbättringsmedel
The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

Träning och kost på ett idrottsgymnasium -En explorativ undersökning som handlar om sambandet mellan kost och träning på ett ishockeygymnasium : Exercise and nutrition at a sportsgymnasium -An explorative survey of the relation between exercise and nutrit
This is an examination report in physical education. It focuses on the relation between excercise and nutrition and how this relation works in an icehockeygymnasium in a midsized city in Sweden. The training ratio for the students are 11-12 times a week which indirectly means that the nutricion is very important to them so that they have the strength to manage both training and school. In this examination report you can read about how the food is composed and how many meals the students are offered through their education program. The persons that I´ve interviewed are the head coach, the president of the school restaurant and three students.The students have practise in the noon two times a week, on Tuesdays and Thursdays.
Establishment and evaluation of a Barley starch isolation method with focus on representability
The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.
